AMD Ryzen 7 5800XT vs Intel Core 9 273PE Comparison

Head-to-Head Benchmarks

The benchmark data delivers a decisive verdict: the Intel Core 9 273PE wins every single head-to-head test in the database. Across 17 recorded comparisons, the AMD Ryzen 7 5800XT records zero wins. The margin varies dramatically by workload, from a narrow single-thread edge to a massive deficit in floating-point and physics tests.

The largest gap appears in PassMark physics, where the Intel part scores 3120 against the AMD's 1355, a 56.6% advantage. Floating-point math shows a similar pattern: 107884 versus 53808, a 50.1% lead for Intel. These two results indicate the Intel processor holds a commanding lead in compute-heavy, parallel workloads that rely on sustained FP throughput. Prime number finding also favors Intel heavily, with 203 versus 119, a 41.4% delta.

Multi-threaded rendering tests tell a consistent story. In Cinebench R23 multi-core, the Intel Core 9 273PE scores 31288 against the Ryzen 7 5800XT's 23794, a 24% difference. The R20 multi-core result mirrors this: 13140 versus 9993, a 23.9% gap, and R15 multi-core shows 3153 versus 2398, also 23.9%. PassMark multithread confirms the trend at 36810 versus 28053, a 23.8% lead.

Single-core results are closer but still favor Intel. Cinebench R23 single-core shows 4417 versus 3359, a 24% advantage. The R20 and R15 single-core tests both show 24% deltas as well (1855 vs 1410 and 445 vs 338 respectively). PassMark single-thread narrows the gap to just 3.2%, with 3650 versus 3535. This suggests that in lightly threaded, short-duration tasks, the two processors are far more comparable, though Intel still holds the edge.

Integer math shows a 32.6% Intel advantage (139410 versus 93942). Random string sorting favors Intel by 20.4% (45098 versus 35911), and data compression by 13.3% (405885 versus 352002). Data encryption is closer at 5.5% (22719 versus 21461), and extended instructions nearly tie at 1.5% (24630 versus 24270). The overall pattern is clear: Intel wins everywhere, with the smallest margins in memory-latency-sensitive and lightly threaded tasks, and the largest in FP-heavy and physics workloads.

Architecture Differences

The two processors come from different design philosophies and manufacturing generations. The AMD Ryzen 7 5800XT uses the Zen 3 architecture under the codename Vermeer, built on a 7 nm process at TSMC with 4,150 million transistors on a 74 mm² die. The Intel Core 9 273PE uses the Bartlett Lake codename, built on a 10 nm process at Intel, with no transistor or die size data recorded in the database.

Core counts differ substantially. The AMD part has 8 cores and 16 threads, while the Intel part has 12 cores and 24 threads. This 50% core and thread advantage explains much of the multi-threaded benchmark gap. Cache hierarchies also differ. The Ryzen 7 5800XT has 64 KB of L1 per core, 512 KB of L2 per core, and 32 MB of shared L3. The Core 9 273PE has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The larger per-core L2 cache on the Intel part is notable, though the AMD's L3 is shared across fewer cores.

The Intel processor supports both DDR4 and DDR5 memory, while the AMD part supports DDR4 only. Both use a dual-channel memory bus, but the Intel part's memory bandwidth is recorded at 89.6 GB/s versus 51.2 GB/s for the AMD. The Intel part includes integrated UHD Graphics 730, whereas the AMD Ryzen 7 5800XT has none. PCIe support also differs: the Intel part uses Gen 5 with 16 CPU lanes, while the AMD part uses Gen 4 with 20 CPU lanes.

The Intel Core 9 273PE has a locked multiplier, while the AMD Ryzen 7 5800XT is multiplier-unlocked. Clock strategy differs as well: the AMD has a 3.80 GHz base clock and 4.80 GHz boost, while the Intel has a lower 2.30 GHz base clock but a much higher 5.70 GHz boost. The power envelope is inverted relative to the core count: the Intel part is rated at 65W TDP, while the AMD part is rated at 105W.

Specification Differences

The socket is a primary differentiator. The AMD Ryzen 7 5800XT uses AMD Socket AM4, while the Intel Core 9 273PE uses Intel Socket 1700. The AMD part belongs to the 5000 series, and Intel's series field is not recorded in the database.

Clock speeds differ as noted: 3.80 GHz base and 4.80 GHz boost for AMD, 2.30 GHz base and 5.70 GHz boost for Intel. The TDP differs by 40W in favor of the Intel part (65W versus 105W). Process node differs by generation: 7 nm for AMD, 10 nm for Intel, with different foundries (TSMC versus Intel).

Cache organization differs across all levels. L1 is 64 KB per core for AMD versus 80 KB per core for Intel. L2 is 512 KB per core versus 2 MB per core. L3 is 32 MB shared versus 36 MB shared. Memory support differs in type (DDR4 only versus DDR4 and DDR5) and bandwidth (51.2 GB/s versus 89.6 GB/s). PCIe generation and lane count differ: Gen 4 with 20 lanes for AMD, Gen 5 with 16 lanes for Intel.

The integrated graphics field is N/A for AMD and UHD Graphics 730 for Intel. The AMD part has a multiplier unlocked; the Intel part does not. Release dates differ: 2024-07-30 for AMD, 2026-03-08 for Intel. The AMD part number is 100-000001582, and the Intel part number is SA4QD.

The Verdict

The recorded data supports one clear conclusion: the Intel Core 9 273PE is the stronger processor in every measured test. Its average benchmark score of 49845 is 66.8% higher than the Ryzen 7 5800XT's 29879, and it holds a higher percentile rank against all CPUs (90 versus 81). The Intel part wins all 17 head-to-head comparisons, with no test going the AMD's way.

The Ryzen 7 5800XT does retain certain structural advantages. It has a higher base clock (3.80 GHz versus 2.30 GHz), a larger PCIe lane count (20 versus 16), an unlocked multiplier, and a lower launch MSRP ($249 versus $549). It also uses a mature AM4 platform. However, none of these factors change the outcome in the benchmark suite. The Intel part delivers higher scores in every category, including the closest margin, PassMark single-thread, where it leads by only 3.2%.

For workloads that demand raw throughput, the Intel Core 9 273PE is the data-backed choice. Its 12 cores and 24 threads, larger caches, higher memory bandwidth, and higher boost clock collectively produce the observed leads. The Ryzen 7 5800XT remains the more economical entry point on paper, but the benchmark evidence shows no workload category where it surpasses the Intel part.

Where Each One Wins

The Intel Core 9 273PE wins in every benchmark category recorded. The largest margins are in physics (56.6%), floating-point math (50.1%), and prime number finding (41.4%). These are compute-bound workloads where the Intel part's higher core count and boost clock dominate. Rendering workloads, represented by the three Cinebench versions, show consistent 23.9% to 24% leads in both single and multi-core tests.

The AMD Ryzen 7 5800XT has no benchmark victories in the database, but its closest relative performances indicate where it is least disadvantaged. PassMark single-thread shows only a 3.2% gap, and extended instructions shows just a 1.5% gap. Data encryption is also relatively close at 5.5%. These results suggest that in lightly threaded, short-burst tasks or workloads that do not scale with core count, the Ryzen 7 5800XT performs nearly on par with the Intel part.

The Intel part's wins in data compression (13.3%), random string sorting (20.4%), and integer math (32.6%) demonstrate broad general-purpose superiority. The AMD part's 20 PCIe Gen 4 lanes and unlocked multiplier are qualitative advantages that do not appear in the benchmark scores. Users prioritizing the highest recorded performance across the full test suite should select the Intel Core 9 273PE. Users constrained to the AM4 platform or preferring an unlocked multiplier may still find the Ryzen 7 5800XT relevant, but the performance data does not place it ahead in any measured category.
